About this Gig
Are you developing a precision measurement device that requires a low noise analog front end and accurate ADC performance?
I will design a custom analog front end (AFE) PCB for sensitive sensor signals, precision instrumentation and high resolution data acquisition systems.
My services include:
- Low noise analog circuit design
- Precision ADC integration (16-bit, 24-bit and higher-resolution architectures where appropriate)
- Instrumentation amplifier and low-noise op-amp circuits
- Differential signal conditioning
- Antialiasing and low pass filters
- Precision voltage references and analog power supplies
- Load cell and strain gauge interfaces
I can work with suitable ADC platforms from Texas Instruments, Analog Devices and other manufacturers, depending on your resolution, sampling rate, input range, noise budget and application requirements.
Applications include:
- Precision data acquisition
- Industrial instrumentation
- Load cells and weighing systems
- Strain gauge measurement
- Biomedical signal acquisition
Please contact me before ordering with your sensor specificacations, target resolution, sampling rate and existing schematics so we can define the right design scope.
FAQ
Can you design a 24-bit ADC board?
Yes. I can design around suitable 24-bit ADCs, subject to the required sampling rate, input range, noise performance and overall system architecture.
Can you work with load cells and strain gauges?
Yes. The design can include bridge excitation, instrumentation amplification, differential inputs, precision references and ADC interfacing.
Can you reduce noise in an existing analog PCB?
Yes. I can review grounding, return-current paths, decoupling, filtering, reference circuitry, component selection and layout-related noise sources.
Which ADC manufacturers do you support?
I can work with suitable Texas Instruments, Analog Devices and other ADC families, depending on the specifications.
Can you design mixed-signal PCBs?
Yes. I can design analog and digital sections with appropriate grounding, routing, decoupling and interface considerations.
Will you provide manufacturing files?
Yes. The agreed deliverables can include schematics, PCB source files, BOM, Gerbers and assembly files.
Can you guarantee measurement accuracy?
Accuracy depends on the complete system, including sensor characteristics, reference stability, amplifier offset and drift, ADC performance, PCB leakage, noise and calibration. I design toward agreed specifications, but guarantees require appropriate verification and testing.
